Bealtaine Healy-Rae-Nua25-something years ago I worked in the same organisation as a woman, let's call her Mary. Different sections, we barely interacted. I moved job, haven't seen sight nor sound of her since.
25-something years later, Mary and I are now working again in the same building, though for different organisations. We need to mail each other, she reminds me of our acquaintance.
Two weeks later, Facebook, in it's "People you may know" thingy, pops up Mary's profile...
